Company News

In the field of precision manufacturing, metal small parts may be tiny, yet they often determine the performance and reliability of an entire product. With years of deep cultivation in the industry, Haina Company not only designs and produces high-precision molds independently, but also directly accepts batch small part processing orders, providing customers with a one-stop solution from mold development to finished product delivery.

What Metal Small Parts Can We Produce?

With a mature processing system, Haina Company can mass-produce the following major categories of precision small parts:

Connectors and Electronic Components: Terminal pins/sockets, electronic inserts, PIN pins, copper cores for probes, pins for aviation plugs, etc.;

Shafts, Pins, and Posts: Micro shafts, stainless steel precision shaft cores, mobile phone hinges, copper posts, dowel pins, knurled pins, motor shafts, etc.;

Fasteners: Various precision screws, nuts, rivets, injection-molded nuts, etc.;

Other Custom-Shaped Parts: Medical equipment accessories, dispensing needles, small pulleys, eyeglass gaskets, lock cores, and various irregular turned small parts.

Whether it's stainless steel, copper alloy, titanium alloy, or other metal materials, we can provide customized processing according to customer drawings or samples.

Complete Processes with Guaranteed Precision

Haina Company flexibly selects the most suitable process based on the material, precision, and batch size of the parts:

CNC Turning and Milling: With CNC Swiss-type lathes as the main force, skilled at processing slender and complex small parts, with processing diameters as small as 0.1mm and precision up to 0.002mm;

Metal Injection Molding (MIM): Suitable for mass production of small parts with complex geometric shapes, such as micro gears;

Stamping and Sheet Metal: Suitable for sheet-like, perforated, or specially contoured small parts, with high efficiency and low cost;

Micro Metal Injection Molding (μ-MIM): For extremely small and complex micro parts, such as micro gears and micro hinges;

Lithographic Metal Manufacturing (LMM): Suitable for high-precision complex parts smaller than 30mm with fine features, with tolerances controllable within ±0.05mm;

Powder Metallurgy: Material utilization rate can reach 97%, suitable for small and simple metal components.

Molds + Processing: Why Choose Haina?

Many customers face this problem: mold factories don't do batch processing, and processing factories don't understand mold design, resulting in high communication costs and long cycles. Haina Company bridges the two stages of mold making and batch production — independent mold design and manufacturing means faster prototyping, more flexible modifications, and more guaranteed batch consistency; meanwhile, directly accepting batch orders eliminates intermediate links, resulting in shorter delivery times and better costs.

Whether you need to develop a new mold or have existing drawings for batch processing of small parts, Haina Company can provide you with professional, efficient, and stable precision manufacturing services.
